Reactivity of Alkyl Halides YouTube

Nucleophilic substitution at saturated carbon centres SN1 and SN2 reactions In 1935, Edward D. Hughes and Sir Christopher Ingold studied nucleophilic substitution reactions of alkyl halides and related compounds. They proposed that there were two main mechanisms at work, both of them competing with each other. The two main mechanisms are the SN1 reaction and the SN2 reaction. …

Nucleophilic Substitution Synthesis of N-Butyl Bromide

The order of alkyl halides towards SN1 mechanism follows the order” Tertiary alkyl halide > secondary alkyl halide > primary alkyl halide. This order is basically based on the stability of carbocations which are formed after the removal of halide ion.

Why do primary alkyl halides generally undergo SN2

In case of alkyl halides, 3 O alkyl halides undergo S N 1 reaction very fast because of the high stability of 3 O carbocations. Hence allylic and benzylic halides show high reactivity towards the S N 1 reaction.

In $\mathrm{S_N1}$ mechanism alkyl halides need to be ionized, so wouldn't it make more sense if alkyl fluoride reactivity were the most, since it is the most electronegative element?

Steric Hindrance. As you add more alkyl groups o the ? carbon atom, the substrate becomes less susceptible to #"S"_N2# attack. A 1° alkyl is sterically unhindered, so an #"S"_N2# reaction is likely.

Steric hinderance. SN2 proceeds via back side attack at an alkyl halide, for instance at methyl bromide, via a five coordinate transition state: If you use a tertiary alkyl instead (replace the 3 H’s with 3 organic groups, R) then the steric hinde...
